AI Technical Summary

Benefits of technology

This technology allows for wireless devices (RFID) with improved functionality by connecting them directly or indirectly via sound interfaces instead of relying on wires from other components like memory cards. By doing this, these technologies allow users to access their personalized identification numbers without having to manually input any details about each device's unique identifier number(UID). Additionally, they have more flexibility when choosing how much space they want to use due to being able to integrate different functions within one piece of hardware while still maintaining compatibility across multiple types of media such as CDMA signals used during voice calls. Overall, this innovation improves both usableness and mobility of electronic equipment equipped with Radio Frequency Identification Devices

Problems solved by technology

This patented technical problem addressed in this patents relates to improving wireless access devices (WLAs) like smartphones and tablets due to their ability to recognize and identify things they have near them easily without having physical keys attached thereto. Current solutions require expensive hardware components and complicated programming processes, leading to increased costs and difficulty carrying around these WLPs.
